Data Summary
The data from each satellite are stored in separate files and directories, by satellite. DORIS data are organized in subdirectories by:
- File content (multi-day files, daily files)
- Satellite
- Year
DORIS Data Holdings
Spatial coverage
Temporal coverage
- Multi-day files from 1990 through present
- Daily data files from 2008 through present
- Coverage: satellite dependent
Data Volume
- DORIS data in multi-day files: ~3-7 Mbytes/satellite/cycle (compressed)
- DORIS data in daily files: ~2 Mbytes/satellite/day (compressed)
Data Formats
- DORIS data in multi-day files: DORIS internal format
- DORIS data in daily files: Receiver Independent Exchange (RINEX) format
DORIS data are available from the CDDIS in subdirectories by satellite and year (for RINEX data).
The starting directory for these files is: https://cddis.nasa.gov/archive/doris/data/
Append the following directory and file names to the starting directory:
SAT/SATdata###.VVV.Z (multi-day files)
SAT/YYYY/SATrxYYDDD.VVV.Z (RINEX files)
as described in the table below.
